In chapter 11, Dean Hamer shows a study of D4DR that relates with novelty seeking behavior. Hamer depathologizes peoples personalities and reassures them that their personality is innate rather than some learned flaw helped them in order to improve their self esteem. Diet and the amount of cholesterol ones intake can also affect personality and behavior. Antisocial and depressed people have been shown to have lower cholesterol levels because cholesterol affects serotonin.
